目的 探讨脑卒中患者照顾者心理健康素养的潜在类别，分析不同潜在类别的影响因素。 方法 2020年7-10月，便利抽样法选取河南省某三级甲等医院287名脑卒中患者照顾者为研究对象，采用一般资料调查问卷和中文版多元心理健康素养量表对其进行调查。采用潜在类别分析将照顾者心理健康素养进行分类，多元Logistic回归探讨不同类别照顾者的特征差异。 结果 脑卒中患者照顾者心理健康素养得分为10（6，18）分，脑卒中患者照顾者心理健康素养特征可分为高素养型（25.0%）、低素养型（55.8%）、低资源型（19.2%）；年龄、文化程度、每天照顾时间、共计照顾患者时长是影响照顾者症状特征分类的影响因素（均P＜0.05）。 结论 脑卒中患者照顾者心理健康素养存在3个潜在类别，医护人员可根据不同照顾者人群特点，实施针对性措施以提高照顾者心理健康素养水平，进一步改善照顾者心理健康。
